Synopsis Dry conditions will prevail across much of the
area through Tuesday with a few record low temperatures for the
coldest valley locations southeast of tucson. Expect scattered
showers and thunderstorms Wednesday, then isolated to scattered
storms mainly east of tucson Thursday into Saturday.

Discussion Our weather is currently dominated by a relatively
strong early season lower pressure system through the great basin
and the rockies. We're on the southern periphery, but still seeing
gusty winds at times this afternoon as well as daytime highs
several degrees below average. Another cool night in store with
temperatures generally in the 40s in cooler eastern valleys, to
50s from tucson into the lower deserts. Not bad for late september
after all those 100 degree days. As a matter of fact, it could
approach record lows in a few colder locations such as douglas and
tombstone.

We'll keep some energy sagging back to maintain a weakness in the
flow even as a large scale ridge of high pressure starts to build
in from the west the first half of the week. It will serve to slow
our warming trend and wrap some moisture from new mexico and
chihuahua into mainly eastern areas around mid week for a chance
of showers and thunderstorms by Wednesday. The weak cut-off will
slowly fill and lift into the front side of the ridge late in the
week before it shears back into higher latitude support next
weekend.

At that point we'll have to see if the eastern pacific ridge
becomes dominant, or if the storm track continues to keep it
upstream and out of the picture. One means near record highs in
early october, and the other windy and relatively cool.

Aviation Valid thru 26 00z.

Expect clear skies for ktus and kols with few to scattered clouds at
5k-8k ft agl through early evening for kdug. Surface winds will be
westerly to northwesterly at 8-12 kts into the early evening hours.

Overnight and Monday morning surface winds variable below 10 kts.

Aviation discussion not updated for TAF amendments.

Fire weather A dry atmosphere will dominate the region through
Tuesday morning. A slight chance of isolated storms will exist
starting Tuesday evening into the overnight hours east of tucson.

Then isolated to scattered thunderstorms will prevail Wednesday
through Friday mainly for areas from tucson eastward. Some lingering
moisture will allow for a slight chance of storms Saturday. 20-foot
winds will be terrain driven less than 15 mph through Wednesday.

Thursday and Friday winds will shift to easterly with afternoon
gusts between 15-20 mph.

Climate The current low temperature forecast at the tucson
airport for tonight is 53 degrees. That would be the coolest low
temperature in september since 1988 when it was 53 degrees on the
23rd. If it only makes it to 54, that would be the coolest low
temperature in september since 2004. The record low for tonight
is 48 from 1913.

Twc watches warnings advisories None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
